Training apparatus

ABSTRACT

A training apparatus consisiting of a rope ( 2 ) which can be passed via a suspended direction reversal means ( 1 ), wherein a first part ( 2 ′) of the rope is arranged to hang down from one side of the direction reversal means, wherein a handle loop ( 3 ) is provided at one end ( 2 ″) of the first part ( 2 ′) of the rope, and wherein a second part ( 2 ′″) of the rope is arranged to hang down from another side of the direction reversal means and is designed to form releasable engagement with a locking device ( 4, 4 ′) of the key way type, so-called “Cleatlock”. The locking device ( 4 ) is secured to the first part of the rope, and the direction reversal means ( 1 ) is selected from the group consisting of: a beam, a bar, a guide tube, a guide channel, a pulley and a suspension bracket.

The present invention relates to a training apparatus consisting of arope that can be passed via a suspended direction reversal means,wherein a first part of the rope is arranged to hang down from one sideof the direction reversal means, wherein a handle loop is provided atone end of the first part of the rope, and wherein a second part of therope is arranged to hang down from another side of the directionreversal means and is designed to form releasable engagement with alocking device of the key way type, so-called “Cleatlock”.

An apparatus of this kind is known from Norwegian Patent 161418. Theknown apparatus has two mutually independent ropes with respectivedirection reversal means, locking device and handle loop, and thedirection reversal means are spaced apart at a fixed distance.

However, there has been a desire to find a training apparatus which isboth cheaper to produce and easier to assemble in certain cases, andwhich permits the installation of just one rope and handle loop or twoor more thereof, depending upon the need of the individual.

According to the invention, the apparatus mentioned above ischaracterised in that the locking device is attached to the first partof the rope, and that the direction reversal means is selected from thegroup consisting of: a beam, a bar, a guide tube, a guide channel, apulley and a suspension bracket.

According to an another embodiment of the apparatus, wherein thedirection reversal means is a suspension bracket, the bracket is made inthe form of a U-shaped structure, and the arms of the U are hooked attheir respective free ends. The distance between the arms of theU-shaped bracket may be adjustable, preferably for suspension from theupper door frame architraves of a door, and the arms may respectivelyhave a perforated portion for the rope for the purpose of forming saiddirection reversal means.

According to one embodiment of the invention, the locking device isequipped with a retaining slot or clamp for the first part of the rope,and the locking device has in connection with the cleatlock part aguide, e.g., a guide belt or guide flap, which covers at least a portionof the opening of the key way part

The purpose of the guide is to limit the movement of the rope out of thecleatlock, i.e., also transverse to the locking part, when the secondpart of the rope is manipulated to adjust the engagement of the key waywith the rope. Advantageously, the guide is elastically yielding.

According to another embodiment, the cleatlock part of the lockingdevice has at an upper end thereof a rope insertion groove for sidewaysinsertion of the second part of the rope, and wherein said guide isdesigned to be positioned after insertion of the second part of the ropein order to limit the sideways movement of the rope part relative to thelocking part of the locking device.

The invention will now be described in more detail with reference to theattached drawings.

FIG. 1 shows an embodiment of the apparatus in a first mode of useaccording to the invention.

FIG. 2 shows a device in a second mode of use in cooperation with asuspension bracket.

FIG. 3 a and FIG. 3 b show details of the suspension bracket as shown inFIG. 2.

FIG. 4 a shows a third mode of use of the apparatus, and FIG. 4 b showsa variant use thereof.

FIG. 5 shows details of the locking device that is an integral part ofthe apparatus.

FIG. 6 shows a modification of the locking device according to FIG. 2.

FIG. 1 shows a direction reversal means 1, e.g., a beam, bar, pulley orthe like which is secured to a support 1′, e.g., a frame structure or abuilding structure as for example a ceiling or door opening, over whichis passed a rope 2 which in a first part 2′ that hangs down on one sideof the direction reversal means at one end 2″ becomes a handle loop 3and some distance above the handle loop is secured in a locking device4, and which at the second end 2′″ that hangs down on the other side ofthe direction reversal means is in releasable engagement with thelocking part 4′ of key way type (so-called “Cleatlock”) on the lockingdevice 4. The rope part 2′ is attachable to the locking device by meansof, e.g., retaining slots 5, 5′, but can of course be attached by meansof adhesive, clamps, rivets etc. Advantageously, there is on the lockingdevice 4 above the locking part 4′ a guide pin 6 for ensuring that therope part 2′″ cannot be easily pulled out of the locking part 4′. Aguide, e.g., in the form of a guide belt 7, which can be elasticallyyieldable, or a guide flap 8, preferable outwardly pivotal againstspring force, is intended to cover at least a part of the opening of thelocking part 4′, so that when the rope part 2′″ is pulled out to theside for upward or downward adjustment of the loop 3, there is no riskof the rope part 2′″ being pulled out so far that it exits the lockingdevice 4.

When the rope part 2′″ is released, it will slide inside the lockingpart 4′ and be held by wedging there by the key way 4″, see FIG. 5.

FIG. 2 shows how the apparatus according to the invention can besuspended from the upper door frame architraves of a door, and FIG. 3shows the suspension bracket in more detail. In FIG. 2 the upper doorframe member is indicated by the reference numeral 9, the door sill bythe numeral 10, the wall structure by the numeral 11 and upperarchitraves (horizontal) by the numerals 12, 12′. The suspensionfitting—or the bracket 13 consists, as shown in FIG. 3 a and FIG. 3 b,of two mutually movable parts 13′, 13″, each of which has an opening13′″ for insertion of the rope 14 (corresponding to the rope 2 in FIG.1). A sliding guide 15, respectively 15′ may be provided at the bottomof the opening. Alternatively, the sliding guide may be in the form of aroller or pulley (not shown). It is also possible that the suspensionbracket, which has an approximate U-shape, may have arms which, e.g.,can be bent away from each other in an elastically yielding manner so asto be able to grip the architraves by pure spring force.

FIG. 4 a shows how, e.g., two or three units 16, 17, 18 consisting ofrope with respective locking device and respective loop, according tothe invention, can be suspended from a common direction reversal means19, e.g., a bar, and where the direction reversal means is mounted on,e.g., a ceiling 20, via hooks 22, 23 which e.g., are spaced 60 cm or 120cm apart.

Although three such units are shown, it would be possible to suspendmore or fewer units according to need. Of course, it is also possible tohave two parallel supports as shown in FIG. 4 b with respectively m andn units for attached to respectively the units 24 m and 25 n, whereinm=1, 2, 3 . . . and n=1, 2, 3 . . . , and wherein m=n or m≠n. As shown,the rope will be passed around a part of the circumference of the beamor bar.

FIG. 5 shows that described in connection with FIG. 1 in more detail,and the difference between FIG. 5 and FIG. 6 is that FIG. 5 shows theguide belt 7, whilst in FIG. 6 this belt has been replaced by the guideflap 8. When the rope 2′″ is to be passed into the locking part 4′ ofthe locking device 4 for the first time, the belt will be held away fromthe locking device 4, but subsequently slipped into place thereon. Whenusing the guide flap 8, the flap is turned (to the right in the figure)to the side and upwards about a pivot point 21 on the device 4, so thatthe rope 2′″ may easily be placed inside the locking part, whereupon theflap is turned back to the position as shown. The flap 8 may bespring-loaded (not shown), but if the pivot mounting allows the flap toturn easily, spring-loading is not necessary, especially if the flapalso has an adapted centre of gravity.
